Teak
Tectona grandis • Exotic/Tropical Hardwood
Grain Pattern
Straight to slightly wavy; presence of coarse, uneven texture with oily feel. Some evidence of ring-porous structure visible in weathering patterns and longitudinal fiber cracks.
Color Description
Golden to medium brown heartwood, likely darkened from UV exposure; sapwood would be pale yellowish-white. Shows typical matte luster associated with high natural silica and oil content.
Hardness Rating
1000 to 1150 lbf (Medium Hard)
Durability Rating
Very Durable; exceptional resistance to rot, termites, and fungal decay. Known as one of the most weather-resistant woods in the world.
Common Uses
Marine decking, outdoor furniture, boat building, heavy construction, carving, and high-end exterior joinery.
Geographic Origin
Native to South and Southeast Asia (India, Myanmar, Thailand); widely grown in plantations across Africa, Latin America, and the Caribbean.
Market Value & Sustainability
Estimated Market Value
$30.00 - $50.00 per board foot for high-quality Burmese or plantation-grown heartwood.
Wood Age Estimate
The sample shows significant weathering and surface degradation (cracking and surface mold spotting), suggesting it has been exposed to the elements for 2-5 years.
Sustainability Status
Listed as Endangered on the IUCN Red List (wild populations); CITES Appendix II for certain origins. FSC-certified plantation teak is the most sustainable choice.
Workability
Generally works well but natural silica content rapidly dulls tool edges. Glues moderately well due to high oil content; pre-boring for screws is essential due to splitting risks along grain lines.
Notable Features
Distinctive leather-like odor when freshly cut; high natural oil and silica content; greasy feel; highly valued for dimensional stability under moisture changes.
Finish Recommendations
Teak oil or penetrating sealers are preferred; polyurethane film-finishes often fail due to wood oils. Sanding and wiping with acetone/solvent is required before any gluing.
Identification Confidence
Medium-High; surface texture, brown color tone, and the specific way the wood has weathered/cracked are highly characteristic of aged Tectona grandis.
